    Cool.

    F/S:
    How are file attributes laid out on the disk? Do you pick up
    the attributes of all the files in a directory in one disk read? Do
    you use this attribute system to store permission bits and the like?

    O/S:
    What is the interface to read an arbitrarily-sized attribute? Do you
    use the same interface to read permission bits?

    NFS:
    Do you always transfer an attribute in one syscall, or do you have an
    open/read/close model? How does the buffer space to store an
    arbitrarily-sized attribute get allocated in user space? (The real
    question here is: does it take two round trips -- one to get the
    attribute size, and the next to do the read?)
